Convert an Apple M4A file (iTunes download, Voice Memo, or AAC audio export) into a standard MP3. M4A and MP3 sound similar at the same bitrate, but MP3 is recognized by every car stereo, walkie-talkie, and old Bluetooth speaker still in service.
M4A is an AAC audio stream wrapped in an MP4 container. iTunes and Apple Music downloads ship as M4A, as do voice memos from iPhone. M4A files are smaller than MP3 at equal quality, but a small number of older car stereos and Bluetooth devices still expect the .mp3 extension.
MP3 is the most compatible audio format ever made. It plays on every device built in the last 25 years, from a $5 Bluetooth speaker to a Tesla, and 320 kbps MP3 is sonically indistinguishable from CD for most listeners. Pick MP3 when you want a file that will simply play, everywhere, without anyone asking what a codec is.
